Perseverance rover, which Landed on Mars In February of this year, it was equipped with two microphones that have already provided nearly five hours of recording of various sounds, such as wind and sound during displacement on the surface of the planet, for example. The recordings are important for scientists to understand the Red Planet in new ways — and of course NASA He invites the audience to listen to the sounds of Mars.
Baptiste Chide, a planetary scientist who studies data collected by microphones, describes that these sounds make the listener feel as if they are on this planet. “Mars sounds have strong bass vibrations, so when you put the headphones on, you can really feel it; I think the microphones will be an important tool for the future of Mars and the science of the solar system.

Perseverance is the first robotic rover to be sent to Mars to be fitted with two microphones – one on the side of the rover and one on the mast, to complement the rock and atmospheric analyzes performed by the SuperCam instrument. To do this, the instrument takes laser images on the rocks and the ground, and then studies the resulting dust with a camera. Since this process occurs hundreds of times for each target, chances are high for rover microphones, which have already picked up the sound of more than 25,000 shots.
As sound travels through the air, some of the recordings have helped scientists learn more about changes in the planet’s atmosphere – and the SuperCam microphone is great for that, because it’s mounted on the rover’s mast and can therefore monitor “micro-turbulence” caused by minimal changes in the air. This information complements the information obtained by the sensors dedicated to the instrument for the Environmental Dynamics Analysis (MEDA) of Mars.
The microphone also allows studies of how sound propagates on the planet. Because Mars’ atmosphere is less dense than Earth’s, scientists had already predicted that high-pitched sounds would be particularly difficult — so much so that recording sounds from Fourth flight of creativity helicopter It was a welcome surprise, as it allowed researchers to scrap two of three different models designed to demonstrate sound propagation on Mars.
